The symptoms of MCI don't normally affect daily life, but everyone’s experience is different.

Symptoms of MCI may include:

  • Memory - Misplacing items or having trouble remembering recent conversations.
  • Attention - Finding it difficult to concentrate, e.g. while watching a TV programme or carrying out duties at work.
  • Disorientation - Confusion about time, date or place.
  • Thinking skills - Problems with planning or completing tasks, e.g. managing money, or cooking a meal.
  • Communication - Problems finding the right words.
  • Mood and behaviour - becoming irritable, anxious, or feeling low.

These symptoms may affect someone with MCI all the time, or they might come and go. This will depend on the underlying cause.

Anyone experiencing any changes to their health, including mild changes to their memory, and thinking, should make an appointment with their doctor as soon as possible. Getting an early and accurate diagnosis is important. You can find out more about getting a diagnosis here.
